Putting together pipes for natural gas to go through

My friend put pipes together using a vasaline like sealant for the black pipes. The pressure did not hold. The pipes have to be taken apart again. WHAT IS THE BEST WAY TO SEAL OFF BLACK PIPE SO IT WILL NOT LEAK? Natural gas has not been put in yet. It has to hold atleast 10 lbs of pressure before the gas company will put it in. Thank you for all your advice....

Mr. Heater Buddy Wall Mount Model MHVFBI10LP Installation

Hi- I appreciate your willingness to take on this do-it-yourself project and have an even greater admiration for your willingness and determination to ask for help in resolving this potentially dangerous matter.
So for your safety and for the safety of your family, please answer the following questions (btw, I downloaded the installation instruction and owner's manual and familliarized myself with the heater you have installed).

1.) What type of piping are you using? (Black iron, copper tubing, gastite, etc.)
2.) Did you use threaded connections?
3.) On the threaded connections, did you use a combination of both, yellow gas line Teflon tape AND a paste sealant, like Hercules real-tuff or RectorSeal? [Don't use white Teflon tape- it is for water plumbing connections. The paste pipe thread sealants are designed for use with LP Gas, as well as other types; they are non-hardening; and make leak-proof pressure tight connections, when used properly.]
4.) After installing your line set BUT before opening the line to run the propane through it, the safest way to check the line for leaks is to run an air pressure test.
That is done between the exterior pressure regulator and the interior gas valve of the heater. The reason you check the line between the regulator and the gas valve is so you don't damage them. They only handle pressures between 4 and 8 ounces OR 1/'4 to 1/2 pound. So when you do the pressure test, DO NOT include the gas valve and the pressure regulator; use a commercial brand of a liquid gas leak detector, or a mixture of soap and water; or a gas stick leak detector- they are inexpensive and can be found at any home improvement center or hardware store.
The actual test requires that you fill the line with 15 pounds of air using a 30 pound test gauge to take your reading from. 15 pounds should be maintained for at least a half-hour (30 minutes). Check with your local building inspector, they may have stricter requirements.

Once you depressurize the air from the line-set, hook up all your connections; turn on the LP gas from the storage tank- you may have to bleed the line from any residual trapped air. Then check all the connections around the gas valve and pressure regulaor, and anything else that was not a part of the air pressure test with the leak detector of your choice.

If you need more help, don't hesitate to ask; I have every confidence that you'll be fine- good luck on your project.

Hello, my name is Jerry I have a vanguard wall heater that is propane but want to use it as a natural gas

Somewhere is an "orifice" that will fix the problem.
This part, if it is accessible, should be near the end of the pipe where the gas is attached to the heater.
Orifices have tiny holes of different sizes depending on the type of gas and pressure used.
Even if you find the orifice and managed to remove it, finding a different one for a different gas may not be easy, or impossible.
Be blessed.

What causes black soot to smoke up our complete house with ventless logs

Take the pilot and burnner assembly all apart and blow it out with compressed air then reassemble and make sure that the air shutter is totally open. The soot is cause by a bad air/fuel misture that is too rich and cause carbon to form from incomplete combustion. If the burner continues to make soot then reduce the gas pressure to the gas log at the pressure regulator.

Need to move the unit by dismantling

Remove the two screws on the side trim. Remove the two top screws from the filter panel. Reach behind the heater and pull the sock down on the vent pipe. unclip the two clamps holding the vent pipe together. Remove the plastic elbow off of the vent termination. Slide the heater to the left to slide the vent pipe off of the vent termination. Remove the gas line after shutting the gas off.

Rinnai R53 Natural Gas Tankless Water Heaters

It sounds like the Rinnai units are working correctly but you've got some plumbing problems.  Any tankless heater has a minimum water flow required to keep the burners going.  If the burners were going with very little water flowing through them to carry the heat away, the heat exchanger could overheat and fail.  The solution is generally to the electronic controls to set the desired temperature and then just use hot water.  Once you start mixing cold water in, you actually reduce the flow of hot water and the burners turn off.  If you are right near the cut off point, the burners will cycle on and off resulting in those very annoying hot-cold-hot-cold showers.  
The fact that you've got those very loud noises indicates some other sort of plumbing problem.  Hooking up two tankless units in series is much more complicated. In heavy draw situations, the second unit is asked to finish heating the water up to temperature when the first unit couldn't quite get it there. Now you're putting hot water into a heater and heating it more.  You have a lot more issues with fluctuating temperatures and pressures within the pipes which could conceivable cause these horrible noises.  Everything's got to be set up right to for things to function properly and it's easy to get something wrong.
From your description, it sounds like a better solution would have been to mount the two heaters in different places. e.g. One in the basement to serve basement and first floor faucets.  The other on the second or third floor to serve those two floors.  Since these units are direct vent (don't use inside air), they can even be mounted in a closed closet as long as the vent can get to the outside.  With this setup you avoid the complexities of a series installation and you also have a much shorter wait time (and therefore less waste) for the fixtures on the upper floors.

The burners are shot. The heavy metal tubes with the holes that the burner flame comes out of, has burnt through. Instead of little rows of holes, there is at least one large hole in it. Unless someone has changed the gas>air mixture, you need new burners.
